Rumors of the long-expected parental timer embedded in the Xbox 360's impending fall update have been picking up steam in the last week or so, with the latest sort-of confirmation supposedly coming from a Guitar Hero III keychain. The included pamphlet reportedly describes the timer thusly:

A simple tool that lets you manage how much time your kids spend on their Xbox 360. Manage in daily or weekly increments. Easy for parents to suspend and add time. Available in December 2007 only through Xbox Live.

The requisite photo of the pamphlet is obligatorily blurry, but with all of the other chatter floating around, even if this is faked, we feel pretty safe betting on the new feature's upcoming launch, particularly given the Xbox 360's new family-focused marketing, like with the Arcade.
